  2. 目前获取链上的交易数据一直获取不到,知道的可以留言下。 https://github.com/FIBOS-Community/fibos-nodes 按照这个走的,连接节点一直报错
  3. 创建新的通证 后进行 锁仓转账,报错no such lock tokens 网上查说是权限问题,这里是由于转账操作 void token::exlocktrans( account_name from, //通证转出方 account_name to, //通证转入方 extended_asset quantity, //通证数量 time_point_sec expiration, //待转出锁仓时间 time_point_sec expiration_to, //待转入锁仓时间 string memo //附言 ) 其中expiration 这个要和 void token::excreate( account_name issuer, // 通证发行账号 asset maximum_supply, // 最大可发行通证数量 double connector_weight, // 连接器权重 asset maximum_exchange, // 最大可兑换(流通)的通证数量 asset reserve_supply, // 未流通通证数量 asset reserve_connector_balance, // 未流通通证保证金数量 time_point_sec expiration, // 项目方预设的项目锁仓期 double buy_fee, // 项目方预设通证兑入手续费 double sell_fee, // 项目方预设通证兑出手续费 account_name connector_balance_issuer //准备金发行方 ) 创建是偶锁仓期expiration是同一个时间。expiration_to, //待转入锁仓时间 这个时间是玩家获得代币后的解锁时间。
  4. 在使用锁仓转账时报错 , invalid cast from type string_type to Object 原文 是 trans.send_inline("eosio.token","exlocktrans",{ from:config.name, to:t.bettor, quantity:‘0.10000 [email protected]’, expiration:s.lock_timestamp, expiration_to:c, memo:r },[{ actor:config.name, permission:"active" }]), 修改成 trans.send_inline("eosio.token","exlocktrans",{ from:config.name, to:t.bettor, quantity:{ quantity:'0.1000 XX', contract:config.name }, expiration:s.lock_timestamp, expiration_to:c, memo:r },[{ actor:config.name, permission:"active" }]),

  12. 今天完成了合约部署后,调用以及网页开发交互,在链上建立了几个表存储数据,前端获取数据使用getTableRows 获取,但是这个函数功能有限,想要更好地操作数据,只有写本地存储 下一阶段就是完成本地存储相关的逻辑,学习(吐槽)下 https://github.com/fengluo/fibos-todomvc 这个demo ,里面太多的todo,新手很容易看不懂每个地方代表的含义,合约中表的类型,开发者账号貌似都是todo,部署合约的账号和调用合约的账号感觉使用两个比较好点,我刚开始看的时候是稀里糊涂的,也可能是刚接触导致的吧。

  14. 今天实现转账功能,A给B转账,B可以在合约中设置监听,当B收到转账时合约会通知监听函数,转账调用的是extransfer ,B合约监听函数即为extransfer加前缀on_,即on_extransfer,之前看文档 https://dev.fo/zh-cn/guide/smart-contract-recipient.html 不是很理解,这次大神指点后恍然大悟,
  15. 今天写了一个合约想在合约中实现转账,自己的合约中调用trans.send_inline('eosio.token', 'extransfer' 一直报错 3090003 unsatisfied_authorization: Provided keys, permissions, and delays do not satisfy declared authorizations\ntransaction declares authority 说没有权限。后来问了大神,果断甩过来一篇文章https://hearrain.com/fibos-smart-contract-subaccount,恩 good
  16. 年前看fibos有一段时间了,刚开始接触一脸懵逼,这是啥,我是谁。哈哈哈 慢慢慢慢地懂了点了,现在注册了账号 在fo钱包里面也玩了几把游戏,也可以解出来线上的合约了(之前发现好高深,会了发现也很简单啊) 开贴记录从这之后遇到的问题以及原因,也算是总结下经验吧

    What is stable coin?

    So far, stable coin in the blockchain world are mainly divided into two types: one is asset mortgage mode, the other is algorithm bank mode. The asset mortgage mode is, using sovereign currency such as US dollar and Euro as the anchoring target, issued in accordance with legal tender at a 1:1 ratio. That is to say, every stable coin in circulation should have one dollar (or other anchored target) as an endorsement of credit and can be cashed at any time. In other words, the value of digital currency is linked to an asset with certain value. This equals to encrypted digitization of legal tender. So far, the main representative currencies are USDT, USDC, GUSD, TUSD, PAX, etc,. The algorithm bank mode uses digital currency or other value targets as collateral and ensures the value of the stable coin by setting different collateral rates. So far, the main representative digital currencies are BitCNY, BitUSD, Dai and so on.
  25. FIBOS

    Why do we need stable coin?

    Encrypted digital currency has a great risk of fluctuation because of its own attributes. If it is used as a value medium to execute transaction or build blockchain ecosystems, the ecosystem will also be affected by fluctuation. Therefore, we need stable coin to ensure value stability over a longer period of time, so that the ecological construction and development of blockchain projects can be better completed.
  26. USDT, the world's first stable coin, was issued by Tether in 2014. Tether was promising to deposit one dollar in Tether's bank account for each USDT issued in order to guarantee a 1:1 ratio. However, in the past four years, it received strong criticism for some of its abuse, including unclear audit, centralization and suspected oversupply. USDC is a stable coin issued on Poloniex Exchange by CENTER, a wholly-owned subsidiary of Circle. Circle is a startup company under the Goldman Sachs Group. Its investors include Bitmain, Goldman Sachs Group, IDG, CICC, CEB and Baidu. It is converted to US dollar at 1:1. USDC is ERC-20 token on the ETH network. The company's operations are transparent and consistent with the global government regulatory framework. In addition to Poloniex, which was purchased by Circle before, exchanges such as OKCoin, KuCoin, Digifinex, Coinplug, XDAEX and CoinEx, as well as many wallet applications have promised to support USDC. In comparison, USDC has better performance than USDT in terms of regulatory compliance, accounting transparency, credit, development potential and technical docking ability, making it more stable and safer. This is also an important factor for us to select USDC as FOD anchoring target.

    如何升级节点的fibos版本

    本文介绍主要如何升级fibos的版本并且如何验证 如何查看fibos版本 如何升级fibos版本 如何查看fibos版本 可以两个方法: 方法一 通过外部查看验证 访问节点的服务: 例如: http://ln-rpc.fibos.io:8870/v1/chain/get_info { server_version: "ced8d7db", chain_id: "6aa7bd33b6b45192465afa3553dedb531acaaff8928cf64b70bd4c5e49b7ec6a", head_block_num: 24030312, last_irreversible_block_num: 24029983, last_irreversible_block_id: "016eab1fc50337a9319ed44b437258bee2c9fa72bad3b4ef48e930f570fecba2", head_block_id: "016eac6844f2e664795c932b0bdb81556b0abf43793c9a17952bb86c211c49a2", head_block_time: "2019-01-15T09:15:45.500", head_block_producer: "superbpusphl", virtual_block_cpu_limit: 200000000, virtual_block_net_limit: 1048576000, block_cpu_limit: 199900, block_net_limit: 1048576, server_version_string: "v1.5.0.1" } 可以知道当前版本 v1.5.0.1 方法二 登陆节点服务器,输入命令 fibos 回车 Welcome to FIBOS v1.5.0.1. Based on fibjs 0.27.0-dev. Type ".help" for more information. > 可以知道当前版本v1.5.0.1 如何升级fibos版本 1. 登陆服务器 2. 直接运行安装命令(更多安装文档,访问官网) curl -s https://fibos.io/download/installer.sh | sh 3. 重启节点服务(如使用screen以下为步骤) 1)输入命令:screen -ls // 列出节点服务所在会话,假设会话名称为bp 2)输入命令screen -r bp //进入 名称为bp的会话 3)进入bp会话后发现节点同步的输入信息。 停止节点服务 ,操作 ctrl+c ,平滑退出 4)命令启动节点 4. 通过上面方法1和方法2验证升级完成 关于screen使用 如发现 screen -r bp 进不了会话,说会话已被使用,可以强制踢下已经访问会话的用户,自己登陆 命令 screen -D -r bp
